Power Stop 03-08 Chevrolet Express 3500 Rear Evolution Geomet Coated Rotor

This is the Power Stop Evolution Geomet Coated Rear Rotor, part number AR8646EVC. It’s a direct bolt-on replacement designed to match the original equipment specifications for a range of heavy-duty trucks and vans, including the Chevrolet Express 3500, GMC Savana 3500, and Chevrolet Silverado 3500 HD. If your vehicle's rear rotors are worn or corroded, this part will restore proper braking function and appearance.

What sets these rotors apart is the GEOMET 360 coating. This isn't just a spray-on treatment; it's a genuine rust preventative coating applied to the entire rotor surface. This coating protects against rust and corrosion, especially in areas exposed to road salt or moisture, without affecting how the rotor grips your brake pads. Power Stop manufactures these rotors to strict tolerances for DTV (disc thickness variation) and runout, which helps ensure a smooth, quiet ride and consistent braking performance. They also match the original equipment's weight and vane count, so you know you're getting a part that's built to perform like the factory original.

Because these are a direct bolt-on replacement, installation is straightforward, requiring no modifications to your vehicle. They are also dynamically mill balanced to ensure they run true right out of the box.
